We excluded teeth with a rotation greater than 10°.
To avoid including teeth needing treatment only for periodontal, orthodontic, or esthetic reasons, we excluded teeth designated for extraction and veneers or crowns placed on anterior teeth, unless caries was recorded.
All teeth (excluding wisdom teeth) were recorded for agenesis of tooth and developmental dental defects using the Developmental Defects of Enamel Index (Fédération Dentaire Internationale 1992).
For each subject the number of retained teeth, excluding wisdom teeth, was counted according to a modified World Health Organization checklist [ 28].
A total of 12.5% of the zone ABR subjects (three males, three females) had missing permanent teeth (excluding wisdom teeth), compared with 4.6% of the zone non-ABR residents (two males, one female).
Dentition status (tooth loss) was assessed by asking "How many of your own teeth do you still have (excluding baby teeth)?" with response categories (1) all (28 32 teeth), (2) missing some teeth, (3) missing many teeth, (4) almost no teeth left and (5) edentulous.
Dentition status (tooth loss) was assessed by asking "How many of your own teeth do you still have (excluding baby teeth)?" The variable was categorized as (1) all (28 32 teeth), (2) missing few teeth, (3) missing quite many teeth, (4) almost no teeth left and (5) edentulous.
Given the insignificance of the non-predictive teeth, we carried out new multiple regression equations excluding these teeth.
In Fig. 14 is shown Al versus Fe for all the samples in this study, and it is observed that a relatively good correlation exists between the logarithmic values of Al and Fe (r2 = 0.89 for the bone samples, excluding the teeth).
A mean morning symptom score and a mean evening symptom score (excluding "sore teeth or gums" and "stomachache") was calculated for each subject for each day.
